Looks and sounds like a scam, I did answer and asked for a name the person on the other end said it was "Cindy" so I asked for a last name no answer, I guess that means she did NOT know. Then I asked what the physical address is, and again did not know. Do know give any information!
Called 6/24/2016 at 2:30 PM. Since I did not recognize the number, I did not answer. However, they did leave a voice mail and it does sound legitimate. Unfortunately I am almost deaf and will have to have a family member listen to the message when they get home. So, I am not going to pass judgement on them until I know more.
